- the network server 10 comprises direct current (DC)/direct current (DC) converters 100 , 101 , 102 for converting DC power converted from the AC power into a prescribed DC power necessary to the video camera 20 , the DVD player 21 , the digital television 22 and the like respectively, as shown in FIG. 1 .
- DC direct current
- DC direct current
- the telephone 30 and the actuator 31 comprises AC/DC converters 300 , 310 for converting the AC power into a prescribed DC power necessary to corresponding device, and the monitoring sensor 40 and the door lock 41 use a battery power to enable an always-on power even in power-off.
- the DC power converted by the DC/DC converter within the network server 10 is supplied to the devices of various kinds included in the network system, for example, video camera, DVD player, and digital television, and the DC power converted using separate AC/DC converter is supplied to the telephone and the actuator, there are problems in which power wiring of the network system is complicate, and power consumption is unnecessarily high.
- the present invention is devised in consideration of the aforementioned situation, and it is an object of the invention to provide a network system which comprises a main power supply means for converting an AC power into a DC power to supply the DC power to the more than one device; and a DC power bus for providing a supply path of the DC power converted by the main power supply means, thereby to supply the power necessary to the network system efficiently.
- the present invention is to provide an auto power control method in the network system using the DC power bus in which a network server monitors operation states of the devices which are classified and managed for each area, and automatically switches off a power breaker within the main power supply means supplying the DC power to any area if the power is determined not to need to be supplied to the area, thereby to prevent unnecessary power consumption.
- the network system using the DC power bus comprises a main power supply means for converting an AC power into a DC power to supply the DC power to the more than one device; and a DC power bus for providing a supply path of the DC power converted by the main power supply means.
- the network system using the DC power bus comprises a main power supply means for converting an AC power into a DC power to provide the DC power to the more than one device; and a DC power bus for providing a supply path of the DC power converted by the main power supply means, wherein the main power supply means comprises more than one power breaker for allowing the DC power to be provided or interrupted to each area; and the network server controls on/off operation of the power breakers by confirming a current state of the more than one device.
- an auto power control method in a network system using a DC power bus comprises monitoring operation states of devices that are classified and managed for each area in the network server if an auto power control operation is performed in the network system using the DC power bus; and automatically turning off a power breaker within the main power supply means which supplies the DC power to any area, if a power off condition is identified for the area as a result of the monitoring.
- FIG. 1 illustrates a structure of general network system.
- FIG. 2 illustrates a structure of network system using a DC power bus according to a first embodiment of the present invention.
- FIG. 3 illustrates a structure of network system using a DC power bus according to a second embodiment of the present invention.
- FIG. 4 illustrates an embodiment of power management information which is stored and managed by the present invention.
- FIG. 5 illustrates an operational flow chart of an auto power control method according to the present invention.
- FIG. 2 illustrates a structure of network system using the DC power bus according to a first embodiment of the present invention.
- a network server 50 located at home can be connected to a video camera 60 , a DVD player 61 , a digital television 62 and the like.
- the network server 50 can be connected to a telephone 70 , an actuator 71 , a monitoring sensor 80 , a door lock 81 and the like, and performs a series of interface operations to transmit/receive signals with each of the devices being connected.
- one main power supply means (SMPS) 90 is additionally located in the network system for supplying the DC power necessary to each device.
- a DC power bus for providing a supply path of the DC power converted by the main power supply means 90 , and on the DC power bus is located a plurality of power outlets C.
- the devices to which the DC power is supplied via the power outlets comprise or are connected to DC/DC converters 600 , 601 , 602 , 700 , 701 for converting the DC power into a prescribed DC power suitable for the corresponding device.
- the main power supply means 90 converts the AC power into the DC power, the converted DC power is supplied to each power outlet via the DC power bus, and the DC power is converted into the prescribed DC power by the DC/DC converter to be supplied if the user connects each device to the power outlets.
- the network server 50 uses the AC power separately from DC power converted by the main power supply means, since it needs relatively higher power that the devices.
- the network server 50 do not necessarily include a plurality of DC/DC converters, and the DC power converted by the main power supply means 90 can be supplied to each device using the DC power bus, efficiencies of power wiring and power supply within the network system are improved.
- FIG. 3 illustrates a structure of a network system using the DC power bus according to a second embodiment of the present invention.
- the main power supply means 90 are located a plurality of the power breakers (i.e., SW_A, SW_B), and the DC power is supplied or interrupted selectively via each power breaker.
- the main power supply means 90 turns on/off each power breaker via interface with the network server 50 .
- the network server 50 classifies and manages multiple devices and sensors located in each of the areas as a one group.
- the network server 50 classifies and manages the devices and sensor located in each of the A area and the B area as a one group.
- the main power supply means 90 will be operatively controlled to turn off the corresponding power breaker automatically.
- the DC power is allowed to be normally supplied to the area A by turning on the power breaker A (SW_A) automatically.
- FIG. 5 illustrates an operational flow chart of the auto power control method according to the present invention. If the auto power control operation is performed through user requests at the network server 50 (S 10 ), the operation state of the devices and the detection state of the sensor which are located in each area, such as for example, a living room, bedroom, library, front door are monitored (S 11 ).
- the auto power control operation is performed which automatically turns off the power breaker supplying the DC power to the corresponding area from amongst the plurality of power breakers included in the main power supply means 90 (S 13 ).
- the network server 50 determines them as the power off condition for the area B, and then automatically switches off the power breaker B (SW_B) that provides the DC power to the area B.
- SW_B power breaker B
- the auto control operation is performed which automatically turns on the power breaker supplying the DC power to the corresponding area from amongst the plurality of power breakers included in the main power supply means 90 (S 15 ).
- the network server 50 determines them as the power on condition for the area A, and then automatically switches on the power breaker A (SW_A) that provides the DC power to the area A.
- SW_A power breaker A
- the network server 50 controls all of the power breakers included in the main power supply means 90 to be turned on (S 17 ), and then interrupts the auto power control operation (S 18 ). Therefore, it is possible to prevent the DC power from being supplied to the area to which the power does not need to be supplied, which results in preventing unnecessary power consumption.
